Add python-pika to install script

Currently pip is pulling a new pre-release version of pika. This
version does not seem to be backwards compatible and is the reason
why uploads fail on new installs.

Since there are packages available for pika on all major distros
we can get away with just installing those as pip will not try to
replace/upgrade them the way it is currently configured.
